Abstract
A vacuum interrupter including a nominally cylindrical insulator having a first insulator portion and a second insulator portion defining a gap therebetween and a nominally cylindrical vapor shield having a first ring of a plurality of spaced apart bobbles and a second ring of a plurality of spaced apart bobbles. A gap ring including a series of spaced apart cut-out notches facing the vapor shield is positioned within the gap. The plurality of bobbles in the first and second ring of bobbles are configured so that the bobbles in the second ring pass through the cut-out notches in the gap ring and the bobbles in the first ring rest on the gap ring.
Claims19
A vacuum interrupter comprising:
- a cylindrical insulator including a first insulator portion and a second insulator portion defining a gap therebetween;
- a cylindrical vapor shield including a first ring of a plurality of spaced apart bobbles and a second ring of a plurality of spaced apart bobbles;
- and
- a gap ring positioned within the gap and including a series of spaced apart cut-out notches facing the vapor shield, wherein, the spaced apart cut-out notches are configured and oriented such that during axial insertion of the vapor shield within the cylindrical insulator the bobbles in the second ring pass through the cut-out notches in the gap ring so as to engage an inner surface of the second insulator portion and the bobbles in the first ring rest on the gap ring.
A vacuum interrupter comprising:
- a cylindrical insulator including a first insulator portion and a second insulator portion defining a gap therebetween;
- a cylindrical vapor shield including a first ring of a plurality of spaced apart bobbles and a second ring of a plurality of spaced apart bobbles, wherein each bobble in the first and second rings of bobbles are radially offset from each other;
- and
- a gap ring positioned within the gap and including a series of spaced apart cut-out notches facing the vapor shield, wherein the plurality of bobbles in the second ring correspond in number to a number of cut-out notches in the gap ring.
A vacuum interrupter comprising:
- a cylindrical insulator including a first insulator portion and a second insulator portion defining a gap therebetween;
- a single piece cylindrical vapor shield including a first ring of a plurality of spaced apart bobbles and a second ring of a plurality of spaced apart bobbles;
- and
- a gap ring positioned within the gap and including a series of spaced apart cut-out notches facing the vapor shield, wherein each bobble in the first ring of bobbles is positioned within an indentation in the first insulator portion and each bobble in the second ring of bobbles is positioned within an indentation in the second insulator portion.
